Onyx Odds Review: Promotions, Banking and Sports Betting
Onyx Odds launched in 2024 as a sweepstakes-based sportsbook. The platform uses two types of currency: Onyx Coins, which are used to place bets for fun, and Onyx Cash, which can be redeemed for real-world prizes. This dual-currency model aligns with sweepstakes compliance standards and helps differentiate gameplay from traditional sports betting.
The free sign up bonus rewards you with 1,000 Onyx Coins after creating an account—no promo code is required. Coins can be purchased using 7 payment methods, including PayPal and ACH. However, prize redemptions are processed only through ACH transfers, which limits flexibility for some users.
During a 4-day evaluation period, we tested the platform by placing bets across available sports to confirm that the experience matched the company's marketing claims.
Onyx Odds offers betting in 7 sports categories: MLB, WNBA, tennis, football, hockey, UFC and soccer. Although the selection is smaller than that of traditional sportsbooks, it still includes key professional leagues, allowing users to wager on mainstream events.
The platform operates legally in 38 U.S. states, with exclusions in states such as Alabama, Colorado, Idaho, Louisiana and Maryland.

The platform implements SSL encryption for data protection. They display a "no-purchase-necessary" disclaimer in the website footer and enforce an 18+ age restriction, meeting sweepstakes compliance standards.

Breakdown of Onyx Odds Ratings
As a regular tester of sweepstakes sportsbooks, I appreciate the simplicity and legality Onyx Odds brings to the table. The clean user interface, PayPal support and low 20 Onyx Cash redemption minimum make getting started easy.
The 250% first purchase bonus outperforms most platforms, but the lack of daily rewards, a referral program and live chat leaves gaps that competing sites have already filled.
While betting runs smoothly across core sports, advanced bettors might miss richer market depth.
Email support delays and ACH-only withdrawals could also frustrate players seeking more responsive service or faster cashout flexibility.
What are the downsides of Onyx Odds?
Here are the key downsides of Onyx Odds.
- Lack of a referral program.
- Limited sports variety: Only 7 betting categories restricts options for diverse bettors.
- No casino games: Pure sportsbook focus excludes slots and table game enthusiasts.
- Slow support responses: 72-hour email reply times frustrate users needing quick help.

When we tested the process, registration took less than two minutes, and the coins were added to our balance right away. With the 1,000 Onyx Coins, you can start exploring the sportsbook and placing bets without spending any money upfront.

No promo code is needed. The bonus is automatically added with your first transaction, so there's no need to track down any coupons or special links.
Review of the bonuses at Onyx Odds
Onyx Odds delivers basic bonus variety with standout first-purchase value
- Instant no deposit coins for new accounts
- Strong first purchase multiplier (250% bonus value)
- Generous mail-in option (5 Onyx Cash per request)
- No daily login rewards program
- Missing refer-a-friend incentives
- Limited ongoing promotions for regular players
- No VIP or loyalty program structure
The bonus framework at Onyx Odds keeps things straightforward without overwhelming new players. The welcome coins gave me just enough to test the waters, though the amount didn’t feel especially generous or provide sweepstakes entries.
The first purchase deal seriously impressed me—getting 25 bonus Onyx Cash for just $10 felt like real value, especially compared to what we’ve seen in other platforms reviewed by Sweepsio.
The mail-in option stood out too, offering 5 Onyx Cash per submission, while most competitors hand out just 2 or 3. Still, the lack of daily rewards and referral incentives felt like a missed opportunity, especially for a 2024 launch.
What are the banking options at Onyx Odds?
Onyx Odds accepts Visa, Mastercard, American Express, Discover, Trustly, PayPal, and ACH for purchases. ACH bank transfers handle all Onyx Cash redemptions for real money prizes.
The following table shows how the Onyx Odds banking options break down.

 Trustly | Instant | $10.00 |

To cash out your Onyx Cash at Onyx Odds, follow these key rules.
- Minimum Withdrawal: You must have at least 20 Onyx Cash in your account to request a payout via ACH.
- Maximum Limit: There’s no stated maximum redemption amount in the platform’s terms.
- Bonus Wagering: Bonus Onyx Cash only needs a 1x playthrough before you can cash it out—right in line with standard sweepstakes rules.
- Processing Time: Withdrawals are typically processed within 7 days of your request.
Review of the banking options at Onyx Odds
Onyx Odds provides diverse purchase methods with limited redemption flexibility
- Seven different purchase options including PayPal
- Low minimum redemption threshold (20 Onyx Cash)
- Standard 1x playthrough requirement
- Trustly integration for faster deposits
- ACH-only redemptions lack variety
- No gift card redemption alternative
- 7-day processing feels sluggish
- $500 purchase cap restricts high rollers
When I examined the banking setup at Onyx Odds, the range of purchase options stood out. PayPal and Trustly, alongside major cards, made funding my account easy.
I liked the 1x wagering requirement—it made accessing my winnings straightforward without added friction. Withdrawing at just 20 Onyx Cash was more generous than other platforms demanding far higher thresholds.
The downside came with redemptions: ACH was the only method available, which felt limiting. Waiting up to 7 days for a payout also tested my patience in a digital-first age where speed should be standard.
What is the Onyx Sportsbook?
Onyx Odds offers 7 sports betting categories with 2 primary betting markets, including MLB, WNBA, tennis, football, hockey, UFC and soccer. These betting markets are powered by their proprietary in-house platform, supporting pre-match and live betting options.
| Sport | Bet Types Available | Market Depth |
|---|---|---|
| MLB | Moneyline, Spreads, Props | Full season coverage |
| WNBA | Moneyline, Spreads, Props | Regular season + playoffs |
| Tennis | Match winner, Sets | Major tournaments |
| Football | Points spreads, Totals | NFL/College coverage |
| Hockey | Puck lines, Totals | NHL regular season |
| UFC | Fight winner, Method | Main card events |
| Soccer | Match result, Goals | International leagues |
Onyx Odds structures their betting platform with grid-style odds buttons for rapid wagering, expandable game details revealing player props and alternative spreads, and a persistent "My Bets" tab tracking all your action.
The interface separates your betting history into filterable categories: All, Won, Cash Out, Open, and Lost - making bankroll management straightforward.
Their proprietary system delivers consistent odds updates without third-party delays, unified betting experience across all sports categories, and simplified navigation without provider switching.
Review of the sportsbook at Onyx Odds
Onyx Odds delivers focused sports betting with limited market variety
- Clean betting interface with intuitive navigation
- Quick bet placement through grid-style buttons
- Comprehensive bet tracking system
- Player props available for major sports
- Only 7 sports categories total
- No casino games or slots
- Limited exotic bet types
- Missing live/in-play betting options
The betting selection at Onyx Odds caters to sports fans only—slots and table games were nowhere to be found.
While just 7 sports categories were offered, I saw the key leagues covered, which satisfied casual betting needs.
The betting process itself felt efficient. I could click odds, set my stake and confirm in seconds. The “More Wagers” section added some depth, especially for MLB and WNBA props.
The platform ran smoothly throughout, thanks to its proprietary tech. Still, as someone who values variety and in-play options, I missed live betting and more expansive markets.

Review of the user experience at Onyx Odds
Onyx Odds provides functional sports betting interface lacking modern support features
- Intuitive betting layout with clear organization
- Mobile-responsive design works smoothly
- Comprehensive bet tracking tools
- Quick access to all betting markets
- No live chat support option
- Missing dedicated mobile app
- Email response times exceed stated limits
- Limited customer service channels
The user experience at Onyx Odds felt tuned for speed. From selecting a sport to tracking open bets, everything flowed without confusion. I found the grid-style odds and the persistent "My Bets" tab especially useful—it helped me stay on top of my action.
But support was where things fell short. I waited nearly three days for an email reply, even though the terms promised 12 hours.
The lack of live chat left me without a quick fix when I needed one. Using the platform in my mobile browser was fine, but compared to today's market, I expect a proper app.
What are the other sites like Onyx Odds?
Sweepstakes sportsbooks similar to Onyx Odds include Fliff, Rebet, Sportzino, Runewager and Legendz. These platforms offer comparable sports betting systems, daily rewards and cash redemption features, as shown in the table below.

How does Onyx Odds compare to other sweepstakes sportsbooks?
Onyx Odds carves a unique niche focusing exclusively on sports betting while competitors like Rebet and Runewager blend sportsbook action with casino games. Compared to the welcome bonus of 600,000 Fliff Coins at Fliff, the 1,000 Onyx Coins feels modest.
The real standout is the first purchase offer—25 Onyx Cash for $10—which beats the usual 100% match found elsewhere.
It also has a lower cashout threshold than most competitors, needing just 20 Onyx Cash to redeem. Payment options are solid, including PayPal and Trustly, but redemptions are limited to ACH only.
On the downside, there’s no daily reward system, app or live chat support, and the sports selection is smaller than what many sites like Fliff offer.
Onyx Odds is a good pick for sports-focused players who want fast, low-barrier rewards. Those wanting more features or game variety might prefer other platforms.
